To all whom it may concern:

Be it known that I, Harmson H. EATON, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Machines forOperating upon the Soles of Boots and Shoes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to machines for operating upon the solesof boots and shoes, and more particularly to machines of this type whichare employed for slashing one face of an insole to increase theflexibility.

The object of the present invention is to provide a machine of this typehaving a simple and eflicient construction which performs the properoperations upon the soles without necessitating any manual labor uponthe part of the operator except the insertion of the soles successivelyinto the machine. With this oh ect1n view a feature of the inventioncontemplates the provision,

in a machine for operating on soles, of simplified and improved devicesfor gaging the sole for the operation of the operating tool and forfeeding the sole to the tool. Other features of the invention consist inimproved mechanism for actuating the feeding devices, in an improvedconstruction and arrangement of the feeding devices by which eitherright or left soles may be fed to the tool, in an improved constructionfor mounting the tools whereby any one tool may be readily selected toperform the operation on the sole, and in certain devices, combinationsand arrangements of parts tending to improve and simplify the operationof machines for making soles. The advantages of these devices,combinations and arrangements of parts will be obvious to those skilledin the art from the following description.

The various features of the present invention will be readily understoodfrom an inspection of the accompanying drawings,

Fig. 15 is a detail in plan of a tool holder showing a plurality oftools each consisting of an opposed series of gradationally arrangedparallel blades; and

Fig. 16 is a detail in plan of a slashed insole showing the hexagonalslashed area formed by the slashing tool.

The machine illustrated is provided with a tool holder supporting aplurality of slashing tools any one of which may be located in properposition to form a slashed area in an insole fed to the tool by a pairof pushers. The pushers are mounted on a recipro eating slide in suchmanner that they may be adjusted differentially in the line of feed soas to locate the slashed area properly on different sizes of insoles,and one pusher shifted relatively to the other in order to adapt thepushers to feed either rights or lefts.

As shown, the machine is provided with a tool holder 1 (Figs. 1, 9 and10) which supports a tool 2 for forming a slashed area in a small sizedinsole, a tool 3 for forming a slashed area in a medium sized insole,and a tool 4 for forming a slashed area in a large sized insole. Each ofthe tools comprises a series of parallel blades 5 (Fig. 15) which arearranged so that a wide blade is interposed between a series of sixnarrower blades decreasing gradationally in width as the blades increasein number from the widest blade. With this construction, a hexagonalarea is slashed in each insole (Fig. 16).

' In the illustrated embodiment of the invention, there are thirty-nineblades, thirteen blades to a tool. The widest blade in each of the threetools is formed on an integral disk 6, and the remaining blades areformed on similar disks 7 there being three blades formed on each disk.The blade disks are separated from one another by a series of spacingdisks 8, one of which is interposed between adjacent blade disks. Theblade and spacing disks are secured by a key 9 to the tool holder 1 andare clamped together between a collar 10 threaded on the tool holder anda collar 11 shrunk on the tool holder. The tool holder 1 is looselymounted on a reduced portion of a shaft 12 so that it may be rotated onthe shaft to bring any one of the tools 2, 3 and 4 into position toperform the slashing operation.

In order to lock the tool holder 1 on the shaft 12 with the selectedtool in operative position the collar 11 is provided with three radialslots 13 which are engaged by three radial lugs 14 formed on a collar 15splined to the shaft 12. The collar 15 is provided with a peripheralgroove 16 engaged by a pair of rolls 17 on a yoke 18 pinned to a rockshaft 19. The rock shaft 19 is journaled in bearings formed in a plate20 which is secured in a slot 21 in the machine frame by a screw 22(Figs. 9, 10 and 11). Pinned to the rock shaft 19 is a handle 23,manipulation of which by the operative moves the collar 15 back andforth on the shaft 12 to insert the lugs 14 into and remove them fromthe slots 13 in the collar 11 to lock and unlock the tool holder 1.

To rotate the tools to bring the selected tool into operationintermittently, the shaft 12 is provided with a gear 24 which is drivenby a pinion 25 on a driving shaft 26 provided with the usual fast andloose pulleys 27. Mounted on av bracket 28 secured to the machine frameis a belt shifter 29 to aid the operative in shifting the belt (notshown) from the loose to the fast pulley to drive the machine from asuitable source of power.

During the slashing operation the insole is supported on a bed roll 30which is rotated at the same rate of speed as the operating tool. Theroll 30 is keyed to a shaft 31 journaled in bearings formed in a yoke 32supported by a vertical rod 33 carried by the machine frame. The shaft31 is con nected to a stub shaft 34, journaled in the machine frame, bya joint 35 permitting a vertical movement of the shaft 31 withoutaffecting the operative connection between the shafts. The shaft 34carries a gear 36 which is driven by a gear 37 on the shaft 12. Toadjust the roll 30 vertically for different thicknesses of insoles therod 33 is provided with a threaded portion 38 which is engaged by a nut39 held, for rotation only, in a slot 40 formed in the machine frame.

The insoles may be fed to the slashing tool by hand, but in order toinsure the proper location of the slashed area on the insole theoperative places the insole on a table 41 carried by the machine framewith the toe end of the insole against a gage 42 and the rear edge ofthe insole a 'ainst a pair of combined gage and feed mein ers orpusher-s 43 and 44 arranged to engage the forepart and shank portions ofthe insole respectively. The gage and pushers are preliminarily adjustedin accordance with the size of insole to be operatcd upon so that whenthe operative places the insole in position on the table with the gageand pusher-s engaging the insole the accurate location of the slashedarea on the face of the insole is assured.

The gage 42 is secured to a slide 45 mounted to slide parallel to theaxis of the shaft 12 in ways formed in a block 46 secured to a flatplate 47 arranged to slide over the table 41 (Figs. 4 to 8). The push-'ers 43 and 44 are respectively carried by slides 48 and 49 mounted toslide in ways 50 and 51 formed in the block 46.

In order to adjust the gage 42 so as to locate the first slash at theproper distance from the toe of the insole the slide 45 is provided witha rack 52 which is engaged by a pinion 53 carried on the lower end of avertical shaft 54 journaled in the block 46 (Fig. 8). The shaft 54 ispinned to a handle 55, manipulation of which by the operative adjuststhe gage 42 in accordance with the length of the insole. in determiningthe proper adjustment for the gage the slide 45 is provided with a scale56 and the block 46 carries a pointer 57 arranged to indicate theadjusted position of the insole on the scale.

In order to locate the slashed area properly in accordance with thewidth of the insole the pushers are mounted for adjustment in the lineof feed. As, there is a definite-- relation between the length of aninsole and its width, the pushers are connected to the slide 45 so thatthey may be moved in the direction of the feed the appropriate dis tancedetermined by the adjustment of the gage 42 for the length of theinsole. To this end the slides 48 and 49 are respectively provided withblocks 58 and 59 which are embraced by slots 60 and 61 formed in the Toaid the operative slide a5 and arranged at the proper angle to themedian line of the slide 45 to impart the proper movements to thepushers. As the width at the forepart has a different relation to thelength of the insole than the width at the shank, the slots and 61 arearranged at diiferent angles to the median line of the slide 45 so thatthe pushers L3 and 44 may be moved difierentially in the line of feed.

After the gage and pushers have been adjusted in accordance with thesize of insole to be operated upon and the insole placed in position onthe table 41 and engaged with the gage and pushers, the latter arereciproated to feed the insole to the slashing tool. To this end theplate 17 is secured to a slide mounted to slide in Ways formed in thetable 41. The slide 62 is connected by a link (33 to an arm 64 looselymounted on a rock shaft 65 journaled in a bearing formed on a bracket 66secured to the machine frame. The arm 6% is normally held pressedagainst an arm 67, clamped on one end of the shaft (35, by a spring 68,coiled around the bearin for the shaft 65, one end of which e11- gagesthe bracket 66 and the other end of which engages the arm 64. The otherend of the rock shaft 65 is provided with an arm 69 which is connectedby a link 70 to an arm 71 projecting from one end of a rock shaft 72journaled in a bearing formed on a bracket- 73 on the machine frame. Theother end of the rock shaft is provided with a second arm 74: whichcarries a roll 75 engaged by the periphery of a cam 76 carried by thegear 2% on the shaft 12. Through the connections described, the slide 62is normally held from movement, under the influence of the spring68, bythe cam 76. When, however, the roll 75 reaches the depression on theearn 7 6, the pushers are aetuated by the spring 68 to feed the insoleto the slashing tool. With this construction the pushers yieldingly feedthe insole to the tool so that breakage is prevented in case of jammingand are positively returned to their initial position. In order that theinitial position of the pushers may be varied as desired, the pivotbetween the slide 62 and the link 63 is mounted on a block 77 mounted toslide in ways formed in the slide 62. The block is bored to receive ascrew 78 held for rotation only on a bracket 79 screwed to the slide 62.

In order that the pushers may feed either coiled around the rod, one endof which is connected to the boss 81 and the other end of which isconnected to a clamp 83 on the rod. Movement of the pusher i l under theinfluence of the spring 82 is limited by a collar 8 1 adjustably mountedon the rodSO to determine the proper position of the pusher 4a forengagementwith a left insole. To position the pusher so that it mayengage the shank of a right insole the clamp 83 is provided with ahandle 85 by which the operative may rotate the rod 80 in the boss 81and slide it forward therein until a latch 86 on the clamp 83 hooks overa dog 87 on the boss 81. The pusher at is thus shifted from the dottedline position, Fig. 1, where it engages a left insole to the full lineposition, Fig. i, where it engages a right insole.

The interval between the return of the pushers to their initial positionand their actuation to feed a new insole to the slashing tool, duringwhich time the operative must position the insole against the gage andpushers, is brief, and consequently there is some danger that anoperative may not po sition an insole properly on the table 11. Toprevent the slashing tool from operating upon a misplaced insole, themachine of the drawings is provided with a finger 88 (Figs. 1, 9 and 10)pivoted on a casing 89 for the tools and normally pressed by a spring 90coiled around the pivot of the finger into the path of movement of theinsole. With this construction if the insole is engaged by only onepusher, the finger 88 will stop the progress of the insole until it isengaged by both pushers and will then yield against the advance of theinsole and ride over the insole.

As the insole is fed between the slashing tool and roll 30 it i removedfrom the pushers by the grip of the tool and roll. To prevent the insolesticking to the slashing tool and thus become wound around the shaft 12,the casing 89 is provided with a series of strippers 91, each of whichis provided With a beveled end 92 and arranged between adjacent bladedisks Figs. 1, 3 and 10).

While the features of the invention have been illustrated and describedin connection with a machine for slashing insoles, it will be apparentto those skilled in the art that the invention is not limited to suchmachines, but that certain features of the invention mav be useful inconnection with machines for performing other operations upon insoles,or, in fact with any machine for operating upon soles.
